PERFORMANCE TEST
4 - 9
Test set-up:
Settings/procedure:
1
-
Apply a 50 Hz sine wave signal of 8V (pp) to input CH1;
2
-
Press the AUTOSET key and adjust the input signal to an amplitude of
8 divisions (CH1 in 1V/div).
3
-
Using the CH1 POS control, adjust the display around the center of the
screen.
6
-
Press the DISPLAY menu key.
7
-
Press the X-DEFL softkey.
8
-
Select ’on’ and ’ch2’ from the X-DEFL menu.
9
-
Use the X POS control to shift the vertical line across the middle eight
divisions of the screen.
Requirements:
-
Verify that the deviation from the ideal straight line does not exceed 0.03
divisions in the center of screen and 0.1 divisions elsewhere.
4.3.6
Vertical deflection; deflection coefficients
The vertical deflection coefficients of channels CH1, CH2, CH3, and CH4 are
checked by means of a calibrated signal. PM3370B/80B/90B: the channels CH1,
CH2 and TRIG VIEW via input EXT TRIG are checked.
Test equipment:
Fluke 5500A mode: volt (Alternative: Square-wave calibration generator PG 506).
